I-Silicon Optical Modulator yeFMCW

I-Silicon Optical Modulatorye-FMCW

Njengoko sonke sazi, enye yezona zinto zibalulekileyo kwiinkqubo ze-FMCW-esekwe kwi-PMCW yimodyuli ephezulu. Umgaqo wayo wokuSebenza uboniswa kweli nani lilandelayo: usebenzisaI-DP-IQ ModulatorisekweImodi enye yecala, ephezulu nangaphantsiMzmSebenza kwindawo ye-Null Null, endleleni kwaye ezantsi kwibhendi ye-WC + WM kunye ne-WC-WM, i-WM yindawo ephantsi ye-90 ye-WM irhoxisiwe, kuphela ukukhanya kwe-WC + WM kuphela. Kwi-B, lr eluhlaza okwesibhakabhaka ngumqondiso we-chirp ye-FM, i-orenji ye-RX ngophawu olubonisiweyo, kwaye ngenxa yempembelelo ye-doppler, umqondiso wokugqibela wokubetha uvelisa i-F1 kunye ne-F2.

Umgama kunye nesantya zezi:

Oku kulandelayo linqaku elipapashwe yi-Shanghai Jiaotong kwiYunivesithi yase-2021, malungaI-SSBabavelisi abasebenzisa i-FMCW ngokusekelwe kwiIimodyuli ze-Silicon.

Intsebenzo ye-MZM iboniswa ngolu hlobo lulandelayo: Umahluko wentsebenzo yemodyuli engaphantsi nezantsi yengalo inkulu kakhulu. I-COUTATA YAMABAKALA NGOKUKHUSELEKILEYO AKUKHO BUNGOZI NGEXESHA LOKUQHELEKILEYO, kwaye impembelelo iya kuba mbi ngakumbi njengoko ukunyuka rhoqo.

Kweli nani lilandelayo, iziphumo zovavanyo zenkqubo ye-LADI zibonisa ukuba i-A / B yindawo yokubetha ngesantya esifanayo, kwaye kumgama owahlukeneyo, kwaye c / d yisantya esifanayo. Iziphumo zovavanyo ziye zafikelela i-15mm kunye ne-0.775m / s.

Apha, kuphela isicelo se-siliconImodyuli ye-OpticalI-FMCW ixoxwa. Ngokwenyani, impembelelo ye-silicon ye-silicon optical ayilunganga njengaleyo yeI-Lino3 Modulator, ikakhulu kuba kwi-Silicon Offilator ye-Silicon ye-Sulicon, iSigaba seSigaba seSigaba / I-Acketion I-Accection Accountition / I-Junction ABitication ayisebenzi kunye notshintsho lwevolthi, njengoko kubonisiwe kumzobo ongezantsi:

Yiyo i,

Ubudlelwane boMbaneI-MUDLALOTORInkqubo yile ilandelayo
Isiphumo siyi-odolo ephezulu:

Oku kuya kubangela ukwandiswa kwemveliso yokubetha umqondiso kunye nokuncipha komyinge we-imeyile. Ke yeyiphi indlela yokuphucula umda wemodyuli yokukhanya kwesilicon? Apha sixoxa kuphela ziimpawu zesixhobo ngokwaso, kwaye musa ukuxoxa ngenkqubo yembuyekezo usebenzisa ezinye izinto ezincedisayo.
Enye yezizathu zokungalingani kwesigaba semodyuli kunye ne-voltage kukuba intsimi yokukhanya kwi-wapegueters isasazwa kwimigangatho enzima kunye nenqanaba lokutshintsha kwenqanaba lahlukile. Njengoko kubonisiwe kulo mfanekiso ulandelayo. Umda ophembelayo onokukuphazamiseka okunzima utshintsha ngaphantsi koko kunokuphazamiseka okukhanyayo.

Eli nani lilandelayo libonisa i-curportion yotshintsho lwe-Dismortion ye-odolo ye-oda ye-oda ye-odolo kunye ne-odolo yesibini ye-odolo ye-odolo ye-STD ngoxinzelelo lwe-clutter, oko kukuthi, i-moduqundency rhoqo. Ingabonwa ukuba amandla okucinezelwa kokuphazamisa i-clutter enzima iphakamile kunento ecekeceke. Ke ngoko, ukubuyela umva kunceda ekuphuculeni umda.

Oku kungasentla kulingana nokuthathela ingqalelo i-C kwimodeli ye-MZM, kunye nefuthe le-R kufuneka kuthathelwe ingqalelo. Oku kulandelayo luqhwitha ijikajika le-CDR3 kunye nokumelana nongcelele. Ingabonwa ukuba incinci yokumelana nongcelele, ukukhulu kwe-CDR3.

Okokugqibela kodwa kungaphelelanga, isiphumo se-selicon modulator ayibi kakhulu kuneso seLinbho3. Njengoko kubonisiwe kumzobo ongezantsi, cd3 yeI-Silicon Modulatoriya kuba iphakame kuneli linbo3 kwimeko yokuyilwa ngokupheleleyo kwesakhiwo kunye nobude bomthambo. Iimeko zovavanyo zihlala zingaguquguquki.

Kwisishwankathelo, uyilo lolwakhiwo lwemodyuli yokukhanya yaseSilicon inokuncitshiswa kuphela, ayinyangeki, nokuba inokuthi isetyenziswe kwiNkqubo ye-FMCW ifuna ukuncitshiswa kwe-FMCW, ukuba inokuthi ifumane izibonelelo zokuncitshiswa kweendleko ezinkulu.
